I'd be interested (particularly after I got my hands on an N900 today.. hmm.. nice.. pitty there is no ALS/line-2 support.. booo Nokia!!!)

I have a working ppp patch that meets my requirements, and a working iptables module.. All this to allow a PPP interface to overlap with another interface.. grrr

The WAP push stuff isn't actually that important from my perspective.. the most important bit for is to allow a connection to be made to the MMS APN with compromising any existing connections (be they PPP or WiFi) it works in a lab situation with a special iptables module AND a patch to pppd.. but the pppd in maemo looks like it is closed source.. so there is a SLIM chance it would clash and cause a service disruption.. slim chance, but a real chance.. and that imho is unacceptable .. If you're going to use a nasty hack, it has to at least work properly
