Being an opensource project under the GPL, it allows developers to add their own backend so that Z-Push can communicate with their groupware solution.
Currently, Z-Push is available with only four backends: the IMAP and the maildir backend for e-mail synchronisation, the vCard backend for contact synchronisation and one for the commercial Zarafa package which is sold by allowing full synchronization of E-mail, Calendar and Contacts. We expect that other backends arise in the near future as the opensource community gets to grips with the new possibilities.
So what does this mean? To see what Z-Push was all about, I installed it on my test server. It's PHP, and I simply uploaded the directory to my server, tweaked the config file, added the required .htaccess and it was ready to rock. It's recommended that Z-Push points at an IMAP server on the same box, but I thought i'd do something a bit different, so I pointed it to GMail's IMAP servers
The result? Exchange Server ActiveSync Push GMail! It worked straight away, and synced my mails. But did push work? To find out, I sent an email from my main email account to my gmail account. From hitting 'Send' in Outlook to the mail appearing on my device took 11 SECONDS! I'd say it worked
If you're looking to hook Server ActiveSync Push Technology into your groupware, then z-push is well worth a look!
