The three other traditional/ancient merged mined coins in the family are GRouPcoin (GRP), CoiLedCoin (CLC) and GeistGeld (XGG).

GeistGeld is still an interesting experiment, for example once I started trying to use Jupiter and Neptune mining rigs with p2pool I ran into a problem with GeistGeld blocks being found so fast that timeouts would occur then file handles would be exhausted.

With the Jupiter I found that if I gradually drove up the total hashing power that GeistGeld as a whole (across its whole network, not just on p2pool or my instance of p2pool) slowly to bring the difficulty up, the out of file handles errors would go away. I have not managed that yet since deploying Neptunes as I do not have enough electricity to allow me the luxury of running a few old Butterfly Labs rigs like I did in the Jupiter era. But I expect that once I get full power to my country-house I should be able to solve it the same way as before.

In theory one would imagine that setting the priority of pools sharing the mining power of a Neptune would let you gradually ramp up the amount hitting the p2pool, or the amount hitting a standalone GeistGeld, or whatever; but in practice not only does the Neptune's panel only offer priorities of 0 through 9 but also it is not even clear whether priority nine gets nine times as much hash power as priority one.

Basically the root of the problem seems to be not merely the speed of the blocks but also the dearth of miners. With very few miners running very few Neptunes, and before the Neptunes arrived only very few miners running very few Jupiters, each Neptune that starts mining it makes a big difference. The problem should thus go away once many miners using many Neptunes and the like have added it into their merge.

p2pool itself though seems to have problems dealing with Neptunes. When my first Neptune arrived I could only see one terahash from it, instead of the expected three point four terahashes, even qwhen only merging the slow-block coins. (That is, it was p2pool giving trouble not e.g. GeistGeld or other fast block coins in the merge.)

What other merged mining software is available as free open source, in particular, something fast enough to deal with Neptune mining rigs?

Also note that I (somewhat on purpose) also kept / keep the auxpow-related stuff in a separate branch from Namecoin proper.  I. e., it is a branch of Bitcoin Core (up-to-date with almost the latest upstream commits) that only adds auxpow, including proper unit- and regression tests.  I think that this could definitely be useful to other coins.  For instance, I also spotted (and fixed) some issues (memory leaks, for instance) in the getauxblock code used by Dogecoin and probably others.

The Namecoin developers are generally interested.
