You may be unaware that the Fortress Eibon game adheres to FLAILSNAILS protocols; what this breaks down to is that you are more than welcome to (and are in fact encouraged to) run your Fortress Eibon character in other games, and conversely characters from other games are welcome to play in the Fortress Eibon games.
You don't have to worry about your character traveling to these other milieus; in the Yam Outskirts there is an office of the Tarn Traveller Aid Society that provides free transport via giant eagle to other realms.
For example, you can use a Fortress Eibon game in a non-Eibon Red Box Vancouver game.
As well, provided that you have a Google+ membership (it's free) and a computer with a microphone and video camera (I think most laptops have this nowadays?) you can play Constantcon (see This and This) games with your Fortress Eibon PC.
Here is the Constantcon Calendar; there are two regular games of note:
Caves of Myrddin - Every Friday morning at 4:30 am; run by Jeff Rients
Nightwick Abbey - Every Saturday afternoon at 1 pm; run by Evan
