Frost is better than UH for multiboxing in PvP because it deals more burst dmg.
When you face serious opponents then they will outheal your sustain dmg and you are only able to kill opponents in burst. UH spec increases your dot dmg and that doesn't help you on landing kills.
I recommend this two hand Frost build:

It's important to have one DK who is speced into imp Icy talons
http://wotlk.cavernoftime.com/item=43825 is a must because it makes your rune tap heal the whole party by 60% HP every 30 sec which is quite OP.
http://wotlk.cavernoftime.com/item=45806 is also important because it gives you a AoE slow.
http://wotlk.cavernoftime.com/item=43547 or http://wotlk.cavernoftime.com/item=43543 are both viable.

Spell priority is quite simple: HB > FS > OBLI > BS
Chains of Ice on round robin when players try to kite you.

Second option is to use DW frost. The advantage over two hand is that it has double runeforge and more KM procs but both require long uptime in melee range to proc.
I prefer two hand because it's initial burst is higher than with DW. Smart opponents will try to kite you a lot so I prefer to deathgrip them and then burst them in 1-2 Hits down. In my experience Two hand does more dmg in that small time window.

P.S. I used to multibox 4 DKs with Smourne. Was tons of fun back then. Especially when you have a pocket healer.
