We saw the same problem in an earlyer state of our concept
development. PHP is not really situated for real time server software
like a SyncML server. This may be working with plan HTML, but starting
with WBX or even OBEX or something like this PHP will loose. So we had
to find another solution.

As far as I know, this was not clearly stated in SyncML 1.0.

This seems to be a common problem with older SyncML implementations,
either in the end user device or the server software. To avoid hassle
with this compatibilty work, we decided to not write our own SyncML
server. This would be much work that has been done by others already.
To test the server aginst all common end user devices would overcome
our ressources by a far extend. So we decided to use Sync4j as
middleware (layer 4 and maybe 5, depending on the device). Sync4j is a
very good engineered SyncML implementation written in Java using the
JBoss application server. It is already stated SyncML compatible at
one SyncML Fest some time ago. The disadvantage is, that the server
administrator has to set up a JBoss server in addition to the phpGW
environment.

We have one :-), see our concept and my new mail in this list.
