We have a new plugin called dap2dap that will allow 2 or more DAP installs to talk to each other.
You can use our dap2dap plugin to automatically forward a request from one dap site to another. This notification will get sent at the time of 'account creation in dap'.
Please note that if a user changes password or profile in one dap site, it will NOT automatically make it to the other dap site. Ability to keep the accounts in sync between the 2 dap sites is a feature we will add in a future version of dap2dap script.
If you want access to dap2dap, it will cost $97. You can contact us via a support ticket here (http://digitalaccesspass.com/support/) and we will send you the payment link to purchase the plugin. After you purchase, we will do a free install of the plugin on your site.
