Does the VM I want to work from need to be offline?
When attaching the disk? yes.
why? You can add new disks to VMWare while a VM is running without any issues. I'm pretty sure you can attach a pre-existing partition as well.
You can do the same in XenServer. At least with Windows as the guest. I haven't tried it with Linux.
You can't however do this if the source drive is running on a separate VM. (That VM must be powered off).
Which is what I did in order to do this.
Sure, as scott said before, I totally understand why you don't mount a VHD to two running VMs - boom!

Right, unless you unmount the source drive first. I don't even think VMWare can reliably do this.
VMware can do it reliably on its side, but it would still hose the data inside the drive.
Right, unless it's a cluster aware OS and Filesystem.

If you unmounted it first? Or was this a system drive?

Just cluster aware filesystem. GFS2, OCFS, VxFS would all work fine.
