The lack of a static IP address can be worked around by using a dynamic DNS service. Freedombone uses [[https://troglobit.com/inadyn.html][inadyn]] , which supports a variety of dynamic DNS providers.
* What are the best microSD cards to use?
There can be big differences in the performance of microSD cards, and the cheaper ones are almost invariably terrible and/or unusable. Sandisk and Samsung currently appear to be the better brands. You can find some performance benchmarks [[http://www.pidramble.com/wiki/benchmarks/microsd-cards][here]]. However, benchmarks like this only give a very rough idea of performance and they can vary significantly between individual cards even within the same brand.
If you're struggling to get good performance out of your microSD card then you might want to consider running from a SATA drive or SSD instead. Some boards such as Cubieboard and Olinuxino have SATA sockets such that you can connect an SSD. It doesn't have to be high cost and the smallest SSD you can find will probably be enough. It's then possible to build an image with the *--sata* option or download one of the pre-built ones and copy it both to the microSD and SATA drive. SSD drives can give a 10x performance improvement over just using a microSD card.
* On a single board computer can I boot from an external SSD or hard drive?
Some single board computers, such as Cubieboards or OLinuxino, have a SATA socket on them which enables an external drive to be connected. This is usually intended for extra file storage, but it is also possible to run the operating system from an external drive. This can have the advantage of significantly increasing the read/write performance and your apps will appear to run more quickly.
