The bit about LH-Jet Volvo's not having any dissolvable parts in their fuel system gives me a great deal of comfort.

Some info for MS equipped vehicles.

1) MSII and FCS (Fuel Composition Sensor) - It's no suprise that the cramped firmware on MSI boxes can't handle the additional tasks, but MSII already has support for the GM FCS. no need to set up multiple fuel tables, it interpolates the correction factors from the regular gas table based on the reading from the FCS. This would allow you to run various mixtures through the tank (full E85, half & half, E10) with no on-the-fly reconfiguring. Lots o' info: http://www.megasquirt.info/flexfuel.htm

2) MSI boxes - I guess no support for the FCS, and possibly there won't ever be. An alternative would be a dual map setup. One map set up for gas, the other set up for E85. You'd have to run the car pretty close to empty before switching over. I think you can rig up an external switch to flip that will switch between tables so you wouldn't have to have a laptop with you. If you were really l337 you could probably also swap ignition tables and alter your MS-managed boost controller at the same time...
