just use Opie so I can sync with my linux machine using MultiSync
This will be difficult.
Firstly you'll need to use the Opie PIM apps rather than the Sharp versions.
Secondly you'll presumably need to support an ftp server on port 4242 (which is what Opie does as that's what Qtopia used to do).
Now you can do the first part quite easily (that's why the feed is there), however you can't do the second bit unless you do some hacking (as Opie won't co-exist with Qtopia).
Your options:
* Look into how multisync is handled and change it to use samba with the Opie PIM apps
* Look into how multisync is handled and change it to use samba with the Sharp PIM apps using dtm2xml
* Look at the Opie code which produces the ftp server, emulate this with a daemon which runs under the Sharp Qtopia version. Then either use the Opie PIM app xml data directly of implement the dtm2xml hack to use the Sharp PIM data.
Best of luck,
