I have been on a project with the purpose of implementing “secure push email” that enables off-site users to access their Lotus Domino mail, calendar and address book using a mobile phone. This is achived using a product called Dynamic Mobile Exchange (DME) from a danish company called Excitor. DME acts as the client on the mobile phone and most importantly as a server in the DMZ that connects the mobile client with the internal Lotus Domino infrastructure. There is a short technical introduction to DME available.

The DME product is a competitor to the BlackBerry products such as the BlackBerry Enterprise Server for IBM Lotus Domino.

I was reminded of this product when reading a post by Budi Febrianto on Funambol: Open Source Domino Sync. The Funambol open source project looks very interesting and I would like to try it out. Funambol is both available as open source and as a commercial offering with differences in features.
