Another idea, instead of making 2 powerful and feature rich download extension why u not join forces with Arno Betz and to make something perfect

Both are respecting each other, but both do they're solo extension.
In the begining Phoca Download was planed to be small, lightweight download manager, now things changes with the people demands and PDL is no longer lightweight or even small download manager.
Arno jD vs Phoca Download features:
Mirrors - Mirrors
Bug Reports - Bug Reports (a bit useless with this linking to guestbook)
JomComment/JComments - JComments
Rates - Rates
Multi-lingual with JFish - N/A
Play (Audio/Video) option - Play audio
Custom Fields - N/A
Own Templating system - Joomla Templating system (Thumb up for PD)
Custom ACL - Joomla ACL (oh crap if someone can control this ACL he is a damn guru)
Modules for
Lates/Updated/Popular with title linking - n/a for PDL
Plugins for Content publishing - almost the same in PDL
That's in short way.
also all feature requests for PDL are similar for jD.....
Both of u are short of time always, and noticed something strange, Joomla 3rd party developers never join for united project, like in XOOPS or PHP-Fusion communities. Everyone prefers the solo way.
Hikari Team and Hika Shop - Our team is a one man
Phoca Team - one man
Joomla Addons (jDownloads) - one man
Ninja Extensions team - one man
DOCMan and Nooku - one man, listed several inactive, the only one active is the current maintainer of DOCMan.
FlashXML Team - one man
Azrul team before the release of JomSocial 1.0 was one man team too.
Attachments team - one man + several translators, i don't count translators as part of any team,
So by extensions.joomla.org
1st is Attachments
2nd is PDL with 192812 views and 4.71 rate
3rd is jD with 231355 views and 4.66 rate (it's 3rd bcz Arno made a mistake to release few internal betas as public)
Clear the bugs only in PD, drop down all feature request for 2.0.0 of PD and join with Arno, he is working on conversion of 1.8.1 to J 1.6
