@Optimizer
Thank you for this very ineresting thread !
We know both the DMOZ has still great influence on authority as soon as the dump is implanted in the google directory itself...this makes it important...not the listing in dmoz itself.
I noticed also that it takes a much longer time to reach the top queries in a certain theme if the site is not in DMOZ.
My experience (US-Site):
New domain (.com) registered May 2004 went online 5-6 May; Google visited the site two days later. Doamin has NOW about 1000 sites listed in G. Very well optimized but not OVERoptimized...NO DMOZ listing (yet), editors probably sleep...
Link-Strategy:
1. Single Link from a PR9-Site with high reputation but NOT themed; link is in a BANNER with Alt-Text "Best
keyword opportunities". The PR9-Site has not more than 3 (!!!) outgoing Links.
2. Single Link from a PR8-Site (old site of the company)
3. Sitewide from a PR6-Network with about 1400 sites (Footer-Link; NOT themed)
4. Sitewide from a PR7-Network with about 15 000 sites (Footer-Link; NOT themed)
5. Sitewide from a PR5-Network with about 2300 sites (Footer-Link; THEMED)
6. About 60 single Links from well-known high PR-directories (paid listings) in the themed category
The mentionned
keyword is a high-competitive term (financial industry) with >14 Million serps and expensive in AdWords (> 5 $ / per click).
Site couldn't be found even with combinations of KW during the first months. ( Not even #1000

)
Now: site has a "fat" PR8 and ranks #5 for
keyword in google.com. It ranks high for industry relevant phrases too !
I think, the point is here the single PR9 Link + the diversification strategy.
It is not a problem to rank high WITH a DMOZ listing...without DMOZ-Listing and a big budget, you have to be patient about 6 months (for a new site) and more (for high competitive singles and phrases) and try to develop an intelligent "low-budget-strategy" --> getting links, content, and waiting...
I love Google !!! If you have a solid link-marketing budget, a good ROI-Strategy and a liitle bit of experience in SEO, it's an easy to become an "authority" in your industry, even without ever beeing listed in DMOZ

The "big boys strategy" is the same as years ago: BOMBING TO THE TOP !!! You can even bomb you out of the "Sandbox", everything is possible (after 4 months, without DMOZ)...This site will surely get #1, there is no doubt...even without DMOZ.
The great point is, the linking PR9-Site excluded Yahoo & Co (only from the ONE site linking)...so NOONE can see the "Killer-Link"...

It's a great "invisibility modus"...
I hope, my case study helps...
