Re: Allied electronic not selling the reference design Raspberry Pi???

Alpha board here: http://www.raspberrypi.org/archives/78

Re: Virtual Memory?

It'll handle it fine; other than the in memory page-mapping and trapping of unmapped access, virtual memory is pretty much all software controlled.

Wait until February 20th, then we'll have all the complaints that it isn't ready for instant teleporter delivery.

For some ATX supplies you may need to put a dummy load on the 12V line as well.

Doesn't USB go both ways?

Nope.

A hub will always have one upstream; any exception is a violation of the standard.

Only "USB On-The-Go" ports can act in either direction.

Re: VLC ported to ARM?

There are ARM packages for vlc listed (in Debian), so short answer is yes.

A longer answer might touch on if there is any support (now or coming soon) for using the GPU features, but I don't have that answer.
