I think you shouldn't regard our hack requests forum as a service like vb.com's support forums. Our hack requests forum is not here to get people's requests coded instantly but they are here to inspire hackers who are looking for nice ideas to code in their free times. It is inevitable that only few of them will be done eventually because coding a hack usually takes a few hour-day work and it is not easily possible to find someone who will volunteerily make them all.
As for your request it has an important technical drawback so it will appeal to only very few people even if coded. The file upload size the server accepts depends on MYSQL and PHP configurations as well apart from vb admin cp restriction and they are set as 2 Mb. by default in most of the servers. So even if you get a hack that increase this in your admin cp, PHP/MYSQL settings of the server will overrule your setting and the hack will be useless until server admin increases the server quotes which is very hard unless you own the server. So the hack will appeal to only people who are on dedicated servers.
