Would this work?

[Particle_Man]

I had this nutty idea of running a short campaign where the players were all Warlocks from Complete Arcane. Aside from the need to have access to healing (maybe start them off at 4th and give them wands of CLW?) are there any obvious problems I should beware of?

Grazzt showing up to take all their souls all at once?

Riding a huge ancient fiendish black dragon, with numerous fiendish otyugh servants, no doubt.

I don't see why it would not work. It could be pretty fun.

It would probably be fine, but since they all have d6 hit points and probably nothing heavier than light armour, they might be laid waste at low levels by something with strong attacks and high touch AC, since unlike most parties, the low level warlocks don't have a chance to really win the fight by tossing around different sorts of attacks (Reflex saves, Will saves, etc), all relying on the touch attacks (or weapon attacks if they so choose) instead.

Sounds very fun to me

Here's my advice for an "all the same class" campaign: Use the Gestalt rule.

So, everyone's a warlock, but everyone has also another class for extra abilities.

If you think Gestalt is too powerful, here are two ways to limit its power:
You may limit Gestalt to just the class features -- leaving HD, skill points, saves and BAB as for the Warlock.
You may allow Gestalt only with NPC classes (adept, aristocrat, expert, warrior, magewright -- nobody's going to choose commoner).

What is the magewright NPC class? I don't recall seeing in the DMG - how could I have missed it all this time?

It's not in the DMG. It's a new NPC class introduced in the Eberron Campaign Setting.

It's an arcane version of the adept. Cast as many spells per day as an adept, use Int instead of Wis, etc.

And for its spell list, it's a trimed-down version of the sor/wiz one, mostly utilitarian. Known spells use a mechanic a bit weird, it gets for free the Spell Mastery feat every few levels (every 3 levels, IIRC), and know only the spells mastered from these automatic feats.
