VirtualBox has shared folders, or you can map a network drive to the
Host OS just like you would in any client/server fileserver setup. If
you're working, as I am, with one machine being the host and guests,
there is no delay.

If you are working remotely, as in a virtualization server, RDP is your
friend for windows. For Linux, ssh for text, or use XDMCP for X.

As for consolidation, we've been able to trim down 12 datacenters of
about 60 servers, with 6 of those being paired windows clusters with HP
MSA500 clusters, down to (4) HP DL380 G7 hosts (2x 6-core Xeons, 72GB
RAM, 4x300GB SAS drives in RAID5), (2) HP/Lefthand P4500 7.2TB (12x600GB
SAS drives in RAID5) mirrored SANs , and (2) Cisco 3750 switches.
