[lucida] Sans serif math with lucida fonts?

[Mau V]

I use Lucida fonts (which I purchased years ago) in Latex docs with

\usepackage[T1,altbullet,expert,nofontinfo,lucidascale]{lucidabr}

Now, if I use them in a Beamer presentation I write

\usepackage[OT1,altbullet,expert,nofontinfo,lucidascale]{lucidabr}

(The OT1 is needed rather than T1 for reasons I do not really
understand but that's it, otherwise I have some problems)

Anyway everything is OK. I get a presentation with Lucida Sans both in
text and in math.

My problem now is to obtain a latex doc which should look like what I
get in Beamer (a sans serif text with sans serif fonts in math, too).

I have tried various combinations (also the package sfmath) but I do
not get lucida sans in math. I copied some code from beamer class but
it doesn't work. I get sans serif in text but not in math or other combinations 
but not what I want (i.e. something which looks like a beamer sans serif 
presentation with Lucida Fonts...)

Is there any user of Lucida who might help?

Thanks!!!
