I've been working on some other improvements that I want to get done before I make a release. I pushed a whole bunch of commits to github if someone wants to have a look.

You have been busy as a bee - looks very good and compiles without problems on my gentoo linux!

nope. it's useless.
this may be true but

all hope for xpm is lost. it's gonna just die down as a botnet coin. Sad
this is your personal opinion which I do not share.

This coin works well although there is no GPU or ASIC miner.

That's because it has some new algorithms in it instead of just a new currency name and 5 parameters adjusted.

But the registration is closed now

Really?

Can you please summarise what can BTCguild do if they hit 51% hashing power?

If you are not able to follow the link I supplied or use a search engine of your choice with the words "51% attack" then I copy+paste for your laziness:

A 51% attack can occur when a single entity has more mining power than the rest of the network combined. This causes concern because it increases the likelihood of a double spend attack and affects the difficulty of the rest of the network. A double spend attack can occur when a transaction is accepted on one chain, and the attacker creates an alternate fork where they still maintain control of the coins. They could theoretically transfer to an exchange, convert to another currency, withdraw it, then create their own fork where they still maintain control of their original coins. They would have effectively doubled their holdings in a short period of time. An additional effect is the lingering network difficulty after an attack. With a several factor increase in speed comes a corresponding increase in computational power required to discover new blocks. If the attacker then leaves the network, as they did in the case of Feathercoin, this will significantly increase the block and transaction confirmation time until the difficulty can be adjusted downward.

I recommend something like btcguild which has the largest share of the pie... 
I personally would not recommend to use the largest pool of all, because btcguild is quite close to 51% hashing power of the whole network. If someone reaches more than 51% hashing power of the network than he is able to split the network in two branches and the do several evil things.  If interested read more here  http://thegenesisblock.com/the-51-attack-what-bitcoin-can-learn-from-alt-coin-experiments/

I'm not saying btcguild would ever do that, I just want to point out that it is not necessary to give them the opportunity by adding my miners to their pool.
