Filesystems:  ext2 and ext4

Vitrualization: Nope.  These are way too small for anything fancy like that.

Addon hardware:
	USB2 ports useful for disk and/or flash drives and other stuff (I don’t do the “other stuff” myself but I suppose there are folks who might).
	They have 1000BaseT ports.  Two ports on the OpenRD Client, one on the SheevaPlug.
	They each have a mini-USB serial port that they use for serial console.
	The Client has a headphone jack.  I’ve used it in the past for listening to streaming radio.  The SheevaPlug has no audio i/o.
	Both machines have SD-card slots that can be used in booting or as aux data storage.
	Both get their uboot from mtd, not mmc, so updating uboot requires re-flashing.
	The Client has 512MB RAM.  The SheevaPlug has the same.

	CPU info for SheevaPlug —

I use the SheevaPlug as a backup DHCP/DNS server for my home network.  The Client is reserved for experimenting.

I don’t currently use NFS on either, but I have in the past.

I’m not sure what you mean by “What kind of compressed ramdisk do you use?”.  As a stab in the dark —

In other words, nothing fancy!

Does that help?
