Twitter has hinted at a new service it is calling @anywhere on Monday at SxSW in what many believe is the company's attempt at taking on Facebook Connect.

Although Twitter has said that it won't release further details until its official developer conference in April, that didn't stop founders Ev Williams and Biz Stone spilling some of the beans via the company's blog and session at the media conference in Austin, Texas.

"We’ve developed a new set of frameworks for adding this Twitter experience anywhere on the web. Soon, sites many of us visit every day will be able to recreate these open, engaging interactions providing a new layer of value for visitors without sending them to Twitter.com", commented Stone on the company blog.

According to the company, site owners need only "drop in a few lines of javascript" to get the new offering up and running.

Before a world wide web roll out, Twitter will be testing the new system with a number of "big" sites that include Amazon, AdAge, Bing, Citysearch, Digg, eBay, The Huffington Post, Meebo, MSNBC.com, The New York Times, Salesforce.com, Yahoo!, and YouTube.

Stone goes on to say:

"Imagine being able to follow a New York Times journalist directly from her byline, tweet about a video without leaving YouTube, and discover new Twitter accounts while visiting the Yahoo! home page—and that’s just the beginning. Twitter has proven to be compelling in a variety of ways. With @anywhere, web site owners and operators will be able to offer visitors more value with less heavy lifting. 

Expect more details in the middle of April.

We will keep you posted.
