Variety is reporting that online DVD rental upstart Netflix (NASDAQ:NFLX) will be visiting our email boxes next year. With video on demand (VOD) posing a grave and gathering danger to his company, Netflix CEO Reed Hastings is going on the offensive.

Alyce Lomax reported recently that Netflix enjoyed an 84% increase in subscribers for its video-by-mail business last year. With 30% of that occurring last quarter, it's clear that, even as Wal-Mart (NYSE:WMT) and Viacom's (NYSE:VIA) Blockbuster (NYSE:BBI) muscle in, Netflix's growth is accelerating.

Alyce also did an excellent job of establishing that VOD and other alternative media like Motley Fool Stock Advisor recommendation TiVo (NASDAQ:TIVO) could threaten the booming business at Netflix. To that end, it is encouraging that Hastings is focused on the long term, looking to lead in delivering video -- not just to control the snail-mail market.

This won't come easily. Studio giants like Sony (NYSE:SNE) and Time Warner (NYSE:TWX) have already established Movielink to download movies to a home computer. But with Movielink charging $2.99 to $4.99 per rental, anyone watching more than one movie a week will likely stay with Netflix. And Movielink has yet to come close when it comes to selection.

Other competition includes Disney's (NYSE:DIS) MovieBeam, which provides 100 new video releases and high-demand movies for a monthly fee of $6.99 to $8.99 (depending on the market), plus $1.99 to $3.99 for a 24-hour rental. Although the offering suffers from the same pricing and availability weaknesses as Movielink, it illustrates the competition on the horizon.

Indeed, when it comes to VOD, Netflix's main weakness may be the extent to which the movie studios seem interested in dominating the digital transmission of movies. Then again, the movie studios failed to dominate the theater business, so why cede the VOD market?

Netflix is free cash flow positive and sits on $135 million cash and a high-priced stock. It could certainly turn to acquisitions to enhance its VOD opportunity. Meanwhile, as it looks for ways to exploit new technologies, the company continues to grow its traditional market (including internationally). This one could have a happy ending.
