p.s. If someone out there is thinking: of course you could do that, if would be trivial if you just did 'X', please feel free to share X with me. Otherwise, we'll have to investigate the open pbx project and the possibility of getting some Quicknet cards...
I have an 8 port conference bridge we can use. Unfortunately I can't provide toll free access. It will be long distance from MN too because I can't bring the PBX.
If there's going to be more than 8 callers, I have another bridge available that will accomodate 32. I prefer not to use that one though.
The neat solution would be to use the asterisk.org software to set up a PBX with a SIP stack. Then international folks could just use the Internet to participate. I've never used Asterisk though, so it's hard to say how much work would be involved setting that up. Is there a local LUG that would be willing to set something like that up? I imagine there's some geek in MN with all the equipment in his closet.
