With all these free colocation offers, I bought a dedicated RPi with 32GB memory card and compiled the latest bitcoind that has ultraprune:
> sudo apt-get install libboost1.50-dev libboost-filesystem1.50-dev libboost-system1.50-dev libboost-program-options1.50-dev libboost-thread1.50-dev libcurl4-openssl-dev libdb5.3++-dev libminiupnpc-dev
> wget https://github.com/bitcoin/bitcoin/archive/master.zip
> unzip master.zip
> cd bitcoin-master/src
> make -f makefile.unix bitcoind
Compilation takes about 1 hour, downloading the blockchain about 20 hours and the bitcoind executable is 43MB!
Other than that it runs really well compared to AWS micro instance, and since RPi colocation is free and AWS micro would be atleast 20$/month with horrible CPU IO wait; this is a nobrainer!
