If you use CF on an IDE interface on the CoCo, it will behave just like
an IDE drive, and you will format it accordingly.  Most of the cards
come formatted with a DOS (V)FAT file system.  If NitrOS-9's msf file
manager can be used with drives bigger than floppies, it might be
possible to use them to transfer data between CoCos and PCs, with the
caveat that when used in IDE mode, CF cards are not hot swappable. 
Otherwise you'll just have to wipe out any existing FAT partition and
format it for RBF / HDB-DOS.

I've used the little adaptors to plug directly into the IDE interface on
a PC motherboard (without even a cable if you get the right gender
connector on the adaptor) and boot LEAF (Linux Embedded Appliance
Firewall, was LRP -- Linux Router Projet) to turn old PCs into NAT
firewall / router boxes.  My dad's digital camera came with a tiny 8M CF
card.  Can't get too many pictures on that.  But you can fit a lot of
LEAF on it.  Pretty slick.
