I like it - the idea of a dvc/$ exchange, particularly for devcoin where it makes sense for a project that appeals to non-techies to have a way to buy them without first having bitcoin. Where my view differs is I don't think it's possible to 'manage' with the depth you suggest without undermining the basic premise.
Probably the most important aspect for a trading exchange is liquidity - i.e. getting as many people with as many bids and offers involved as possible. Doing anything to restrict that will limit pricing and trading and leave the fund carrying the constant risk of having to make up the other side of trades. If you limit members to people who basically know about it, we can pretty much assume those people will be those earning or holding devcoin. Which means they will be sellers.
But it still needs buyers. Who will the buyers be and where will they get the $ from? I guess that would mean the $ have to come from the fund, perpetually, which to go full circle seems to undermine the idea of a real exchange with real prices, and is likely to lead to perpetual fund losses b/c it may be the only buyer.
The alternative would be to get basic dvc/$ going - just a normal exchange. If/when it proves to work with enough interest and liquidity then it may be possible to create a general fund that works to build an actual investment model. One option would be to see if one of the existing exchanges is able to add dvc/$, although pragmatically the fact that only really bitcoin has this might imply it's too early?
I will be exploring it a bit more, Ive also asked in a couple of places for some advice in the areas I have no prior knowledge.
On your devtome suggestions article. Also very good ideas and similar to some thoughts of my own. This is limited right now by expertise and time. Rather than type it out again here's what I wrote before to explain. If a regular with PHP skills was willing to take up the ongoing job (and it would have to be a long-term commitment), and maybe if a couple more detome admins were added, then a lot more is possible. This also depends on the site hoster and others being ok with whoever's involved in maintaining plugins etc.
Ok... well..I dont know if regular means talkative or long time contributor but Im sure I have talkative covered

I have enough basic php skills to manage the SQL databases for the websites I build/manage and have had to teach myself to fix errors so I'm always up for learning more. I am pretty confident I can work with the Dokuwiki format and there seems to be a heap of support articles/documentation to help as well.. Can I put my hand up for exploring this further and maybe getting it done?
