Informed rebuttal of VBR disadvantages appreciated, VBR always rocks, when it comes to lossy compression, right?

As already mentinend in this thread some fanboy over at the offical Pioneer forums is making claims that VBR sucks (here and here) in that it needs more processing power compared to CBR and for various other reasons.

I would like to have a well written rebuttal of that statment based on facts so Pioneer might reconsider putting VBR support into their upcoming DJ equipment. I've ripped all my 1000+ CDs to VBR and I wouldn't want to reencode them just because Pioneer doesn't get it right. Thanks!

Well, I'm sorry but after finding out about Pioneer's VBR limitation my frustration with apparently flawed development processes of huge companies got the best of me (again). People on my blog keep reminding me of workarounds (most of which I'm already aware of) but it's the fact that I need a workaround (like with my Sony) that's ticking me off in the first place.

So when I saw the way the argument goes on the Pioneer forums I wanted someone with knowlegde about the technical issues set the record straight. My opinion is this:

a) a full-fledged MP3 player has got to be able to work with VBR or be renamed
b) properly encoded VBRs are in no way inferior to CBR

Since Pulse as a regular seemed to be leading the discussion on VBR over there with opinions rather than facts I was afraid some Pioneer developers might take this for granted and shun the idea of properly implementing VBR support in future hardware.

It appears to me that Pioneer has gotten it all wrong. It's similar to what's going on at the moment with DVD standlones and USB support. Since USB-HDDs use the same protocol as USB sticks those players can playback media from HDD as well. But some 2.5" HDDs draw more power from the slot than the 500 mA specified so they can't gurantee them to work which simply makes them say it's not possible. Pioneer's hardware does playback VBR but it's officially not supported, you cannot seek in those files and you don't get the remaining time (both vital for a DJ).

So I would expect them to properly implement support for VBR while at the same time making it clear in the manual that this applies only to properly encoded files (proper seek index and stuff). Of course one would have to check playback of each file prior to public performance which I would do even for my own encodes.
