To Muslims thinking about joining TVI Express: is it halal?

I am not the one who posed the question, but a news blogger in Brunei, apparently a pretty important person.

There are sufficient doubts about the company's "fitness" regarding the shariah (sp?) law, which governs all Muslim behavior, that it may NOT be advisable for a Muslim to join TVI Express until the doubt has been cleared up by a shariah scholar or a committee of scholars who specialize in interpretation of shariah for business.
