I use doggcatcher on my android phone and I have an iPad as well. and the biggest thing I miss on my android phone is the absence of a podcast client on desktop which will download podcasts there and sync or stream to my phone. doggcatcher already has the last bit, the only thing lacking is a desktop client. one could always use existing ones. i believe miro is open source and could be integrated in some way so that one can stream downloaded podcasts from my pc via miro to doggcatcher. its impractical to download a video podcast file on a mobile. if one only had the option to download these on a PC and stream it to the mobile device!
do think about it.
