Reason for Suggesting:

If you have large bases with multiple crafting stations where XP is needed, having it accessible at those locations would be very useful.

• The XP obelisk itself can hold an apparently unlimited amount of XP. You can extract this to a tank, but doing so isn't a good idea because then you have finite storage.
• If you have multiple obelisks, you can connect them to a central obelisk for storage, but then you can't see how many levels you have available unless you to go the storage obelisk.

Suggestion:

• Create an XP-specific fluid "tank" which has a digital readout of the number of levels stored, and isn't limited on the amount of XP it can contain.
• Enable Remote Awareness Upgrades for the tank or its conduits, so that connected XP obelisks can display the number of levels available in the tank.

Possible workaround for 1.7.10: Fluid Storage Bus from Extra Cells => Liquid XP in your ME System and therefore easily distributable

Even better, linked obelisk with shared tanks?
