According to everything I can find and ascertain, DMOZ is fairly well a dead issue. I wouldn't worry about it.
Other than a single link from a PR 8 site, that's about all its worth any more. The data isn't being used that much anywhere of significance any more. I notice google built the noodp tag about 2 years ago, at least partially to counter the stale information in the dmoz directory. If you don't use that tag in your meta tags - you should, by the way. (<meta name=”robots” content=”noodp”>)
Bruce Clay's Search engine relationship chart no longer shows them as feeding data.

Google now has their own directory. Back in 2003 they fed google data every week.
That was a time when it was a necessity, but I think that time has long passed, and their "technical difficulties" a couple years ago made it all the worse, as it shrinks into web obscurity.
I know a bit about this - I was an editor there for a few years, for 6 states, spent
hundreds of hours editing florist listings, with the intent of giving myself an advantage. Myself and other editors rejected many floral sites for what I now believe to be truly bs reasons, other than to gain an advantage. The justification was - I was the one spending the hundreds of hours. No one with a wire service site was allowed, which it inferred somehow made them less of a florist. (the standard cut and paste reason for delisting or non inclusion was "template site lacking unique content") I no longer believe having a wire service site is any kind of judgement of quality of a florist, and many great florists have and use them.
When they finally fixed the tech problems I think it was already shrinking into a non issue. The tech problems exacerbated and hastened its demise, as the data grew very stale.
There are only 478 US florists listed there now. Oregon shows only 23 florists (I believe I added most of them), the third largest - California the largest with only 62, next to Florida which has 58. Many states show 3, 4, 5 florists in the whole state. The criteria for inclusion makes it inaccessible for about 95% of florists. It never was "friendly" for the public to use - go there and search for "florist yourcity, state"

and it can't find you - the only way is to drill down thru the categories and not many people even know how to do that, let alone have the will to take the time figuring it out.
Maybe if it gets bought it will get revitalized by paying editors, but it just became too much volunteer work for many of us to continue.
So the short version is - IMO - If you're not already listed, I really wouldn't worry about it, unless you think a single link from a good PR site will push you up enough to matter.
Just bloomz opinions, and you know...
