Sideline from Yahoo is a free Adobe Air-based tool that will enable you to search for and locate tweets based around a particular term. For example, if you wanted to search for 'vnunet.com', simply set this up as a particular term of interest and Sideline will show any tweet that references this search term. Sideline from Yahoo is based on Adobe Air so will work with any operating system that Air supports. Note that it's not a tool for adding your tweet to a conversation.
