Roll20 and Syrinscape workaround adviceAnd for those lazy not to click
"Here's some info you might like if you use Virtual Tabletops! Thanks sooo much user Jim for this info!
Using Syrinscape with a Virtual Tabletop such as
Roll20.net The easiest way to do this is to use an additional desktop as another "participant" in the game. Whether using
roll20.net
or Google Hangout or Skype, if you have another account that can join
the group, I'd just use my second laptop and set the Mic/LineIn to "What
You Hear" and leave it running so others can hear whatever sound comes
from my laptop. Other players can then either choose to listen or mute.
You might also try using
mixlr.com
(or some similar free, amateur internet radio host, like a shoutcast
station) and use the highest baud rate for streaming. Most of the audio
streaming sites can be configured as private or invite only, and
although most don't let you stream for more than a few hours per day, it
would be enough for a good online gaming session.
Good ideas! Huh!

Would still like to see some official integration between Roll20 and Syrinscape though regardless of this workaround.
