Considering CeroWrt as a free software project, it may be the right time to measure each of the following:

1. Amount of manpower/cash required to keep the project afloat and developing.
2. Added value, which exists due to its unique properties.
3. Population of developers willing to invest their manpower/cash.
4. Population of users willing to use the outcomes as long as it helps them stay focused on their own needs.

Accounting and distributing CeroWrt daily duties will make some space for a day job, at least part-time, which is very important. Focusing the 2nd item to help users understand the point of switching a Netgear box to CeroWrt will help the community grow naturally. The deliverable could come like this:

"Here is a small automatic test, which will measure the jitter, delay and RTT of your connection through a Netgear box to a server far on the Internet. Record these numbers and repeat the test after flashing the 3800 with this stable CeroWrt release. Let us know the difference and consider these unique features, which are available in CeroWrt only:
* something good
* something else
Have fun!

Picking some antenna types other than omnidirectional may be another solution, but it depends.
