It's a shame that you couldn't host a game solely between PocketPC's -- I envisioned a glorious commute of the future where everyone gets on the subway, sets their WiFi card to Ad-Hoc mode and plays PQ multi. (Although this is the distant future, so maybe PQ3 multi?) But you'd need PQ to be able to host for that. Oh well.
Today I decided to go a step beyond just connecting to my desktop and actually had a friend host a quake server at his house. This proved to be quite a challenge for a less-than-ovbious reason: To connect to a WAN address, you have to enter the IP manually. To do that you need to have access to the keyboard, but PQ covers it up except when the console is down. I'm hoping that Dan can make the keyboard pop up automatically for text feilds (as it does now for the console) in some future release of PQ, but until then I've figured out a workaround:
Step 1: Open PQ.
Step 2: Minimze PQ.
Step 3: Open some program that has the 'bring up keyboard' button in the lower left.
Step 4: Open PQ.
When PQ opens again, the button will still be there. You can now access the keyboard whenever you like, including at the WAN IP prompt.
NOTE: If there's some way to connect to a specific IP from the console you could use that, but I don't know if you can.
When I played that game I also found out just how serious an advantage people with graphics accelerators and mouses and keyboards really have, and it's pretty serious. That makes me wonder... is it possible to restrict access to a Quake server based on the client? If it were, you could set up a public server that accepted connections ONLY from PQ clients. It could even run only maps designed specifically for PQ. Does such a server exist already?
Oh, Dan, now that there's OpenGL for the PPC, when can we expect Pocket Quake 3?

I guess it will be more plausible with PPC .NET when MS finally bothers to optimize an OS for XScale with ARM v5, though by then there will probably be a yet faster processor that they won't support. I'm not going to hold my breath for that, but I can always dream of PQ3...
