none that I know of,
yes some can speak Coptic at some degree
take for example those videos that was created by batros
http://kame.danacbe.com/index.php/topic,261.0.htmlI can and do read Coptic books (but never without a dictionary)
some people claim to be speaking coptic fluently, take for example mona zaki
http://kame.danacbe.com/index.php/topic,95.0.html but she is not native speaker, her grandfather learned Coptic and used it at home
he made success at some degree but I doubt that they have ever spoke fluently
if that is all not enough, the way you (and mona zaki and most Coptic speakers) pronounce Coptic words is not correct.
this way of pronunciation was invented by church, true Coptic never had letters like "th" and "V"
so the language we use to pray in our churches is not the same as the one our grandfathers used
