完全可行！！！！！就是即时聊天系统，特别可行，用node.js 配合socket.io库就可以实现
基于node.js 的socket.io 实现的例子百度一下很多，比如这个http://www.cnblogs.com/Wayou/p/hichat_built_with_nodejs_socket.html
晚上回家我那有更好的例子
你看看微信和QQ怎么实现的就知道了，视频聊天呢都可以。
QQ有网页版，淘宝旺旺有网页版，微博也有私信聊天界面……
这个是很常见的功能吧。
PHP+前端技术是可以实现的。
前端如果只考虑支持HTML5的浏览器，可以用WebSocket。
前端如果可以用Flash，可以用XMLSocket。
前端如果考虑兼容性，可以用JS实现AJAX架构（心跳包机制）。
前端如果想实现消息的即时性更好，可以用JS实现Comet架构（长连接轮询机制）。
通常推荐用后两种方案，详细的可以百度下。
PHPWebIM是Swoole官方基于PHP Swoole扩展和Swoole Framework开发的WebSocket网页即时聊天工具.
PHPWebIM支持WebSocket+Comet2种兼容协议,可用于所有种类的浏览器包括IE.

使用 webSocket 就可以实现了（虽然这个回答比较简短，但是是个可行的方案）
