I personally have never done it, however there shouldn't be a problem doing it.
Mead is almost all water and simply distilling it would require a purchase of a distiller at the LHBS. They use to sell them at sears, or I am sure you can also get them at amazon.
Simply the process of distillation is heating the liquid so that all the water and impurities, have dissipated and all that is left is distilled mead. For a red wine it would also be called Brandy.
So making a mead Brandy is entirely possible. In fact there is a place new to Chicago will be starting to sell distilled mead. I think there is a thread on this forum devoted to this proposition.
I have even thought about making my own personal mead brandy for consumption with friends and family.
Try it and write about it here. I would like to know more about it and others here would be interested also.
