With you doing all the heavy lifting, I felt obliged to pitch in a tiny

Guessed so - it may still be tough to pull off. Not sure TT RAM can be 
used for video on the TT.

I'm not even sure whether I'll make it to Europe at all this year. 32 
hours of air travel with a toddler might be too much really.

SCSI disks are usually not huge - space may be a premium.

It'll be hda on ARAnyM and Falcon, sda elsewhere.

There's a reason the hddriver authors could ask for money for their 
drivers :-)

That's assuming a small enough kernel, and already installed system with 
all modules on the disk.

Right - that would explain it.

I have replied to him (I think) asking for details, and got zilch in 
reply. I'm happy to try again.

Feature creep - I'll look at it again.
