Hi again, Daintiness - great to hear you would like to share your camera view with your friends
I've never set up my nest box live but I know of others who have which may help you with this (see links below). I must stress I have no experience to go on for recommendations.
To share nestbox'hedgehog footage with my blog visitors, I upload videos to YouTube and embed them in my blog for others to see. I use a programme to edit the footage but you could Windows movie maker to do this for free (see video of doing this http://www.youtube.com/watch?v=ZrFJLeF0tA0).
By uploading to YouTube you could choose to share your videos with friends only (I'm sure there is a setting for that). You don't need to make them public. You could then send links to your friends via email/mobile.
http://www.camstreams.com/ (don't know if this is still active - its supposed to be free but don't know if it's reliable)
http://wildlifegadgetman.com/?page_id=26 (you could email Jason about him streaming a live cam for you. His site suggests he does but the link didn't work when I tried it just now - I don't know if it would cost you)
http://www.wildlifekate.co.uk/ (Kate could probably make a suggestion for you if you were to email her)
Sorry that's all I've got for you just now. If I come across any others in the next few weeks I'll come back here with a link
Best wishes for a successful brood of Blue tits - 11 chicks fledging would be a great result!
