My solution to my problem is to create a menu "eula" with sequence 0, that would trigger a server action.  Whenever a user logins, it will go to the first item of the menu item.  Thus by doing this, it will alway trigger the eula form I intend to display

<menuitem id="main_eula_menu"
            name="EULA"
            sequence="0"
            action="ir_actions_server_eula_trigger"
/>

the menu would then trigger the server action below upon login.

<record id="ir_actions_server_eula_trigger" model="ir.actions.server">
            <field name="sequence" eval="5"/>
            <field name="state">code</field>
            <field name="type">ir.actions.server</field>
            <field name="model_id" ref="model_eula_eula"/>
            <field name="code">action = self.trigger(cr, uid, None, context)</field>
            <field name="condition">True</field>
            <field name="name">EULA Agreement</field>
        </record>

the form below is used to allow user's to agree or disagree the eula.

<record id="view_form_eula" model="ir.ui.view">
            <field name="name">view_form_eula</field>
            <field name="model">eula.eula</field>
            <field name="arch" type="xml">
                <form>
                    <div>
                        <field name="content"/>
                    </div>
                    <footer>
                        <a href="/eula/agree" class="oe_button">I agree</a>
                        <a href="/web/session/logout?redirect=/web" class="oe_button oe_highlight">I disagree</a>
                    </footer>
                </form>
            </field>
        </record>

the Eula model  which has a trigger method to be called by the server action

class Eula(models.Model):
    _name = 'eula.eula'
    name = fields.Char()
    content = fields.Html(readonly=True)
    agree = fields.Boolean(string="Agree", help="By checking this, you agree to the EULA.", default=False)
    @api.multi
    def trigger(self):
        _logger.info("Enter Eula Trigger")
        return {
            'name': 'EULA Agreement',
            'view_type': 'form',
            'view_mode': 'form',
            'res_model': 'eula.eula',
            'res_id': 1,
            'type': 'ir.actions.act_window',
            'target': 'new'
        }

Finally a special route and controller to remove the eula menu if accepted.

class Eula(http.Controller):
    @http.route('/eula/agree/', auth='user')
    def index(self, **kw):
        _logger.info(self);
        model_datas = http.request.env['ir.model.data'].search([('module', '=', 'eula'), ('model', '=', 'ir.ui.menu')])
        for model_data in model_datas:
            model_name = model_data.model
            model_id = model_data.res_id
            model = http.request.env[model_name].search([('id', '=', model_id)])
            model.sudo().unlink()
            model_data.sudo().unlink()
        eula = http.request.env['eula.eula'].search([('id', '=', 1)])
        eula.agree = True
        return werkzeug.utils.redirect("/")
