You only need to make certain that the file is in your elected shared folder...
Also, don't forget that the way that Gnutella Network actually works means that there is no certainty that even someone living next door to you is going to instantly find you within the network...
Your alternatives would be to learn how to make so-called 'direct connects' with your friends using Gnutella Network...
This is not really crazy complicated but you have to be nuts to try to do it without also using a chat channel of some type... Yahoo or MSN or whatever... You really will want to be in real-time chat contact while you are trying to establish a 'direct connect' and while you are trying to maintain any 'privacy' on that connection...
Remember... With Gnutella Network you and your friends can create your own 'private network' within Gnutella Network...
(Some idiots out there may go a bit ballistic at my last words, but ignore them... As long as you are still sharing generally within the network, using 'direct connects' can be a very easy way to INCREASE the total numbers of sources for rare files !!!
If you or a friend has something interesting, new or rare to share and... and you are able to get together with a few other friends and all share the interesting stuff quickly, then you and your friends are going to become a sudden increase in sources throughout the overall network, right ?)
There are many posts on this subject here in the various forums so have a long search and read first...

If, you are instead referring to a privately made video that you wish to share amongst your friends but not to the general public...
There are more secure alternatives...
