Were there any comparable offerings from other manufacturers?

Not really. It was quite an advanced bit of kit for the time (2004/5) and had most of the functions of modern race control systems. The internet racing malarkey was fairly useless though and Hornby really neglected to push the main functions of the system.

It did have a lot of bugs which the updates never really sorted out and Hornby were by then putting their limited resources into Digital so it soon became an ex-parrot with the remaining stock being sold off very cheaply in 2009. Total production and sales were allegedly only 1000 units and a significant proportion were completely faulty so quite a rare beast these days.

Couple of caveats when you use it:
blue Scalextric guides won't register laps and hot motors (25,000 rpm+) will cause system overloads.
