For either of them, can you use SIP? SKYPE? SSH? If so is there anything special that has to be done to use them? What speed can someone expect?

Cellcom at least uses non symmetric NAT for the IP address they give you when you use their service, with the result being that not tunneled SIP will be impossible. Skype should work as well as IAX2, but I haven't tried either of them.
SSH works jut fine of course (and so openvpn).
And of course, which cellular modems are supported by Linux and at what
speeds?

I use the Sierra AirCard 850. It works beautifully with Linux. The speed is limited by Cellcom, not the modem.

Thanks in advance, Geoff.
